Doc update related to - Matplotlib Colorbar conversion not supporting

[priyatharsan]

Related to this issue - https://github.com/plotly/plotly.py/issues/552 Probably because Scatter doesn't have colorbar attribute.

Documentation needed to be updated for the Matplotlib based tutorials that implements colorbar

• [ ] https://plot.ly/ipython-notebooks/baltimore-vital-signs/
• [x] https://plot.ly/matplotlib/colors-and-colormaps/ - must be fixed along with HTML to ipynb update in #802

Getting an error like this:

Python 3:

Dang! That path collection is out of this world. I totally don't know what to do with it yet! Plotly can only import path collections linked to 'data' coordinates

Python 2:

ValueError: 
    Invalid value of type '__builtin__.bool' received for the 'tickmode' property of layout.yaxis
        Received value: False

    The 'tickmode' property is an enumeration that may be specified as:
      - One of the following enumeration values:
            ['auto', 'linear', 'array']

@cldougl , I looked through https://plot.ly/ipython-notebooks/baltimore-vital-signs/ and it's working as it should (in plotly v2.7 and python v2.7 at least).

Should I make another issue to remove the warnings and update it to be python3 compatible and then close this issue?
